Description

VOUTA

Analog Output Voltage of DAC A. Buffered output with a nominal full-scale output range of ±4.096 V. The

output amplifier is capable of directly driving a 5 kΩ, 200 pF load.

No internal connection

REFA

Reference Voltage input. Reference input range is 1V to 2.1V; programs the full-scale output voltage.

REFA = 2.048V for specified performance.

REFB

Reference Voltage input. Reference input range is 1V to 2.1V; programs the full-scale output voltage.

REFB = 2.048V for specified performance.

No Connect.

REFGND

Reference Ground Return for the Reference Generator and Buffers.

TEMP

This pin provides an output voltage proportional to temperature. The output voltage is 1.4V typical at

25°C die temperature; variation with temperature is 5mV/°C.

BIN/2sCOMP

Determines the DAC Coding. This pin should be hardwired to either DVCC or DGND. When hardwired to

DVCC, input coding is offset binary. When hardwired to DGND, input coding is twos complement

(see Table 7).

1 Internal pull-up device on this logic input. Therefore, it can be left floating and defaults to a logic high condition.
